Arthroscopy of the shoulder is a well-established diagnostic procedure which has widespread application. Advances in technology and the search for more minimal invasive surgery will always offer new techniques in any surgical field. Robotic technology is such an advance, offering technical advantages over standard laparoscopic approaches. The aim of the present study is to test whether robotic surgery can be used while performing shoulder arthroscopy or not. ⋯ Robotic shoulder arthroscopy seems feasible in a cadaveric model but has some significant limitations at this time. A clinical application could be performed as diagnostic arthroscopy and as simple arthroscopic surgery until more specific instrumentation is developed. It may also enable the surgeon to perform more complex and precise tasks in restricted spaces.

Robotic-assisted laparoscopic prostatectomy (RALP) is usually performed in steep Trendelenburg position, which can be associated with cardiac impairment due to positioning and capnoperitoneum. This study investigated haemodynamic consequences and cardiac function in this type of surgery and evaluated the hypothesis that steep Trendelenburg position and capnoperitoneum results in haemodynamic and ventricular impairment. ⋯ The steep Trendelenburg position may improve haemodynamic function and does not deteriorate left or right ventricular function during RALP. However, mitral valve insufficiency may be aggravated by positioning and capnoperitoneum.
